DTIC ADA534283: Real-Time Physiological and Psycho-Physiological Status Monitoring (Suivi en Temps reel de l'Etat Physiologique et Psycho-Physiologique)

Dismounted warfighting groups are increasingly recognizing the benefits of knowing the medical status information that body-worn computerized physiological sensor systems can provide. This report on real-time physiological and psycho-physiological status monitoring reviews: a) Physiological monitoring system architectures, methods for managing noisy sensor data, and algorithms and models used to define physiological state; b) Thermal strain assessment methodologies, including an innovative method for estimating core temperature; c) Human hydration, and markers and methods of assessing hydration state; d) Altitude illness, from Acute Mountain Sickness (AMS) to High Altitude Pulmonary and Cerebral Edema (HAPE/HACE), and the possibility of monitoring acclimatization status under operational conditions at high altitude; e) Sleep, and how circadian disruptions and sleep deprivation can lead to physical and mental fatigue and degraded cognitive performance; f) The relationship of heart rate variability and fatigue; and g) The use of ambulatory physiologic monitoring for combat casualty care. In addition, a prototype physiological monitoring system is described. Future research should: i)
